Hi again
another question - I see in here that the tooltips can be set with layertooltips and a color can be set for the tooltip:
<https://github.com/Georift/lets-plot-kotlin/blob/master/docs/tooltips.md?plain=1#L282>

but it seems that there is no option of doing this in the IDE:
```tooltips=layerTooltips()
                   .anchor("top_center")
                   .color("cyan")```
is it a doc mistake or I am missing something?

Not sure, but it looks like a deprecated API that is no longer in use. Currently you can customize tooltips with themes, see:
